exile target creature you control.
Whenever you cast an instant or sorcery spell,
you may put a quest counter on Escape Captivity.

Captivity and sacrifice it: Return target creature

Search your library for an Equipment card, put it
onto the battlefield, and attach it to that creature.
Then shuffle your library.
